As you’re reading this I’m flying across the Atlantic home, to what I hear is a sunny London! I’ve had an amazing experience following the scientists as they look for new species and experiment with REX in the waters around the Bahamas.

 

The scientists will have a lot of work to do when they get back to the Museum with all their samples. They will be busy checking to see if the species they have found here in the Bahamas are actually undescribed and new to science and we'll keep you updated with any results.

 

I hope you’ve enjoyed following the blog as much as I have enjoyed writing it. Highlights for me have been seeing the amazing footage that REX was sending back to the control room, helping the scientists sieve for worms in the mangroves, sharing in their ups and downs as they looked for the experiments and, of course, waking up with an amazing view every morning!

Now it’s time for the credits… there are lots of people to thank for making this happen!

 

Firstly to Stephen, Martin and Honor for allowing me to spend 10 days out of the office. To everyone in the Learning department for their support but especially my fantastic colleagues in the Nature Live team – Jo, Ana Rita, Natalie and Tom.

 

Extra special thanks to Tom and Natalie for hosting the shows so professionally and dealing with any technical problems so gracefully – I bet the audience had no idea what was happening behind the scenes! Also to Verity Nye, who came up from Southampton, and Museum scientist Geoff Boxshall who were our anchors in the studio during the live-links. Geoff, great news, we collected you a sample from Hatchet Bay and I have a big bruise on my leg to prove it!

 

Thanks to Adam and the special effects team for making sure the live-video-links back to London worked so smoothly.

 

To Jonathan for setting up the fantastic live-chat sessions and to Grace for organising the entire schools component of the fieldtrip. It was so great having that interaction with pupils.

 

In the Bahamas we have a lot of people to thank – firstly Janet and Harvey Higgs and the rest of Nick’s family for being so hospitable – no request was ever too much, and we requested a lot!

 

Big thank you to our fantastic skipper Howard, not only was he a great Captain, he’s also a great cook too – preparing freshly caught fish while we were busy with REX...

Thank you to Kendra from the Bahamas Marine Mammals Research Organisation who supplied the whale bones that we sank for our experiments. I bet the sharks are grateful for that too!

 

P1000320.jpg

Above: Kendra joined us to see what we had done with her donated whale bones!

 

The science team have been amazing and so accommodating to my requests; whether that was asking to interview them, taking part in Nature Live and other events or my personal favourite, ‘how do you spell that again’?!

 

Big thanks to Diva, Leigh, Nick, Helena and Gill for being great field companions. Thanks to Tony for always being at the ready with the camera and making those live-video-links happen from this end.

 

Finally, a big thank you to Adrian for making this whole fieldtrip possible! I’ve had a fantastic time following science as it happens in the field – capturing their discoveries and sharing them with you - and I hope you’ve enjoyed reading about it!

 

I asked Adrian to sum up the trip for us…

Today we invited the local school children to SWIMS (Spanish Wells Institute of Marine Science, remember!) to have a look at what we have been up to. They really enjoyed sieving for worms in the sand but I think they thought we were all crazy for wearing summer clothes in March!

While we were sieving with the pupils we came across a tiger shark tooth. Yet more evidence that they are abundant in these waters ... but we still haven’t managed to actually see one on this field trip!

Above: More evidence of sharks - but still no sighting

 

After the schools children left the team got back to work looking at samples under the microscopes. The big question on everyone’s lips was whether the goat skull we found yesterday had any Osedax on it.

 

The scientists spent a long time studying the skull and debating the findings. They can see tubes on the skull that belong to a worm but that doesn’t necessarily have to be Osedax.

 

Adrian is not convinced that it’s Osedax at all. He believes they may have found another polychaete worm from the family Terebellidae.

 

EZ4H0032.jpg

Above: Terebellidae found on the goat skull

 

However, if it is Terebellidae then it shouldn’t be living on a goat skull. Usually they live in limestone crevices but the goat skull may be close enough for it to call home. Basically you can see how sometimes discoveries can create more questions than answers! I don’t think we are going to get a conclusive answer before we get back to the Museum.

 

We only have one day left here in the Bahamas but here are some of the great pieces of footage that REX has shot over the last week.

This is the moment that REX went over the Grand Bahaman Canyon that goes down to 3,000m …

 

 

For me, some of the most amazing footage we have seen was when REX went through the purple bacteria in Ocean Hole. Also, look out for when REX meets the goat skull…

 

 

Tonight is our last night in the Bahamas. We’re saying goodbye in an appropriate manner – a drink on the beach at sunset!

Today we had an early start to begin the 200 mile round-trip to Ocean Hole on south Eleuthera.

 

P1000457.jpg

The inland lake called Ocean Hole

Ocean Hole is an inland lake, a mile from the oceans, that rises and ebbs with the tides. When we arrived we attracted a large gathering from a local school and Nick spoke to them about what we were doing with REX and why.

 

P1000474.jpg

Above: Nick doing some educational outreach

 

Amongst the crowds that had gathered was Ronald Horton, who is the administrator of Ocean Hole, and I asked him his thoughts…

 

 

 

 

REX went in and immediately descended to 40m. He didn't see any mermaids but when it was looking at the rubbish littering the floor of Ocean Hole it stumbled upon a goat skull.

 

REX carefully brought the skull up to the surface and, although it’s not a whale bone, everyone was excited at the idea that Osedax maybe be living on the bones, albeit in the most unlikely of places. It would have definitely made up for the earlier setbacks with the sharks!

 

P1000481.jpg

Above: Helena inspecting the goat skull

 

The team will now spend the best part of tomorrow trying to determine whether the worms found on the goat skull are Osedax. I’ll keep you posted!

 

When REX went in for a second time he descended to 38m. As he ventured down he saw this amazing purple glowing layer. From where we were sitting in the control room it looked very similar to the aurora. We nicknamed it the purple haze but what it is actually a type of bacteria.

 

None of the team had ever seen anything like this before. We didn't record any difference in temperature as REX descended so Adrian thinks that this purple haze may indicate the point when freshwater and sea water meet. Either way, the bacteria looked amazing on film…

 

 

 

 

Tomorrow we’re going to be analysing the goat skull under the microscope to see if we can find any evidence of Osedax. If the worm is on the goat skull it wouldn’t have been how we expected to find it, but every cloud…

Our last Nature Live event from the Bahamas was a bioblitz with Helena and Diva. It was great fun as we trawled the beach, against the clock, to find whatever we could for the family-friendly audience.

With yesterday’s shark incident still at the fore of our minds, we set out to recover the 2nd package and to try and find and recover the 3rd package.

We made visual contact with the 2nd package late last night but it was getting too dark to bring it to the surface. So we returned to the spot today and hauled it up on to the boat.

 

The shark damage was obvious but we got a piece of good news…it hadn’t taken all of the whale bones! We found a small bone still attached to the basket which lifted everyone’s spirits. Helena was particularly excited – even though it was a small piece she will be analysing it under the microscope for any evidence of Osedax.

 

helena.jpg

Above: Helena was very pleased that some of the whale bones had been recovered

 

After lunch we moved on to the 3rd and final package which was perched on the edge of the Great Bahamian Canyon. If it wasn’t were we left it six months ago then it had slipped into the abyss, far out of REX’s reach. It took nearly 2 hours to locate it and the control room was full of people waiting to catch a glimpse of it in the blue. This is the moment Nick spotted it…

 

 

After the initial excitement of finding the package we quickly realised that it would be a challenge to recover. At 55m deep, it was too deep for divers to go down to get it so we had to make sure that REX had a good grip on it so as it didn’t drop as it came to the surface. We carefully raised it to the surface and Nick and Leigh jumped in to retrieve it.

 

boat.jpg

Above: Despite its appearance we were very glad to see our basket!

 

Using REX meant that we knew, even when the experiment was still on the sea floor, that it too had been visited by a curious/hungry shark as all the whale bones were missing. But this time all the wood was still attached to the baskets. We now know that sharks, if given the choice, don’t like eating wood! The best bit was seeing how many lionfish were surrounding the basket…

 

 

That wrapped up our time on the boat and it was great that we managed to recover all 3 experiments using REX, it’s just a shame that sharks got to the them before we could!

 

baskets.jpg

Above: This sums it all up beautifully. Lesson #1: Sharks like whale bones.

 

Tomorrow will be a long day of microscope work but the day after we head out to Blue Hole to drop REX down to nearly 200m. Will we get to finally see sharks instead of just their bite marks?!

We started the day early with another successful round of live-video-links to the UK to talk to school pupils and the Nature Live audience in the Attenborough Studio.

With the weather improving everyday, we got the news we'd been waiting for yesterday - that we could finally head out to sea and look for the experiments that were laid down six months ago. We left port full of hope for the day ahead and with a large supply of seasickness tablets.

 

It took nearly an hour to get out to the first site and there was a lot of waiting around but once REX hit the water, the excitement set in. I couldn’t believe I was getting just as excited about finding these whale bones as the scientists were. Would we find the first package and would we find Osedax?

 

 

It wasn’t long before we found the package however it wasn’t exactly how we left it…

 

 

When the remains of the basket were pulled aboard we saw that there were no whale bones left, let alone Osedax. I had no idea that whale bones were that attractive to sharks but the shark bite marks on the plastic basket were conclusive evidence!

 

Although everyone was a little disapppointed that the experiment had been lost they quickly started working on the other creatures found living on the basket. They found many different polychaetes and as I type they are still analysing them under the microscope.

As we moved on to the 2nd site many in the team were left wondering, what state would the next experiment be in?!

 

Adrian did a great job of piloting the ROV and we found the second package in a relatively short period of time. But REX delivered some more bad news…

 

 

We were asked today by a student during our live video link if Jaws could happen. Well, I suppose if you’re a plastic basket it most certainly can!

 

We're heading out tomorrow to look for the third package which is deeper down at 55 metres. Will it be sharks - 3, scientists - 0?

 

And don't forget you can speak to Helena and Diva live in the Bahamas today at 2.30pm in the Attenborough Studio.

Welcome to...

We are all waking up really early - around 6am when the sun comes up. After breakfast we loaded up the golf carts with spades, sieves and sampling jars and we were ready to go panning for worms. We ventured out to the mangroves on the other side of the island, where we were relieved to find that the wind was much less intense.

 

helena.jpg

Above: Helena is ready to find some worms in the Bahamian sand

 

Once we reached the marina we had to get out to the sampling site and what better way than to kayak. Then we had to do some serious digging, put the muddy sand into a bucket and kayak the samples back to the shore. To be fair, Nick did a lot of the hard work!

 

It was then up to Diva and Helena to sieve through all the mud, this may sound easy but when you’re looking for tiny creatures you have to be very precise and it can take quite a while.

 

 

We found a few large creatures, such as sea cucumbers and a giant anemone, but the really exciting stuff is only visible under the microscope. Helena was really excited as she thinks she has found a new species of the marine worm Ophryotrocha under the microscope! Obviously we can't tell for sure until we get back to the Museum but it's great to think that it might be so.

 

 

Above: Could this be a new species of the marine worm Ophryotrocha?

 

One of the other highlights of the day was that Gill got to see Cassiopeia jellyfish for the first time in the wild!

Above: Cassiopeia made Gill’s day!

 

After lunch (which was rice and beans!) we spent a good part of the day testing REX before we send him into the deep later in the week. Adrian and Leigh set up a mission control in a repurposed bathroom on the beach and we sat and watched REX manoeuvre through the shallow sea grass beds.

Here is when REX met a lionfish…

 

 

On Thu 8 Mar (which is tomorrow for me as I write this) we'll be linking live to the Attenborough Studio so do join us if you can!

The Museum has recently acquired a great bit of kit that allows us to complete our work in the Bahamas. It’s a remotely-operated vehicle that we lovingly call REX (short for Remotely-operated vehicle for Education and eXploration).

 

rov-REX-in-the-water.jpg

 

It has the ability to go to depths of 200 metres and we’ll be using it to retrieve the experiments that were laid down late last year. It has a robotic arm too and apparently if you can play XBox you can operate it pretty easily!

 

robot arm.jpg

 

The really special thing about REX is that it has a HD camera attached to it so we can film amazing footage of the sea and the life within it. It’s important for scientists to observe how animals behave in their natural environment, especially when it comes to creatures like jellyfish, as when you bring them up to the surface they look like amorphous blobs.

 

Like I’ve said before I’m really looking forward to seeing sharks and going by the video shot last year I won’t be disappointed!

One of the objectives of our field trip to the Bahamas is to see if a species of the bone-eating worm, Osedax, can be found there, which would be a first for science. However, if we're to find Osedax worms in tropical waters we need to lure them to us.

 

We know that these bizarre creatures bore into the bones of dead whales that have fallen to the seafloor. Finding a whale skeleton naturally in the waters in the Caribbean could take weeks or months and although a stay that long sounds like an attractive prospect it wouldn't be the most economical. Instead, the team thought to sink pieces of whale bone and wood to attract the worms.

 

So, in October 2011, Adrian Glover and Nick Higgs went to the Bahamas to do just that. Here is a picture of the experiments...

The baskets were dropped to the sea floor at different depths; one each at 19m, 30m and 55m.

 

Here is the experiment that was lowered at 19m in October - will we be able to find it on our return?

Now, 6 months later, we're going to retrieve them and hopefully in that time an Osedax species will have colonised them and we'll find the first record of the worms in the Caribbean. We’ll keep you posted!

Will we find Osedax in tropical waters?

On Friday and Saturday, I introduced everyone else who is going to the Bahamas, and now there’s only me left:

 

Being a Nature Live host, I have always worked closely with Museum scientists but I’ve never had the opportunity to accompany them on a field trip. I feel extremely lucky to be going to the Bahamas and it will definitely make a change from being in the Attenborough Studio at the Museum (see me hosting a recent session about the Bahamas with Adrian Glover here).

 

The really exciting thing for me about this field work trip is being able to engage our visitors with Museum science as it happens, live, on the other side of the Atlantic. Hopefully it will help people see we are much more than the ‘Dinosaur museum’!

 

Highlight?

A highlight for me would be to see sharks, even if it is through our eyes in the ocean - the remotely operated vehicle, REX. I also hope we find a new species of Osedax so that I can have first dibs on naming it! (I realise I won’t get the honour but a girl can dream!)

 

Anything worrying me?

I am a little worried about the possibility of getting sea sick. I don’t do well on boats – a fact I have kept to myself until now!

 

I hope you’ll follow our trip and check in for the latest on our journey...

What do you study?

At the museum, my project looks at organic falls - these are large packages of food like dead whales and trees that sink to the seafloor. Once on the seafloor they provide lots of food and shelter for many deep sea animals and a whole new ecosystem is formed. My background is mainly deep sea biology but growing up in the Caribbean has allowed me to have good knowledge of tropical biology also.

 

What are you most excited about seeing/finding on the trip?

It would be incredible to find some Osedax worms on the bone packages we put down in October when we were last there, as they would be the first ones found in tropical waters. I’m also really looking forward to seeing some sharks as the Bahamas recently declared their national waters as a shark sanctuary.

 

Where have you been previously on field work?

I have previously done some field work off Bermuda and more importantly, I was part of the scientific team that journeyed to the Cayman Trench to discover the world's deepest hydrothermal vents. I've also done some work in my home of Trinidad and Tobago.

 

What is your best experience whilst on field work?

The best experience I've had while on field work would be when we saw the first live footage of the world’s deepest hydrothermal vents and the amazing animals living around them. It was so amazing to realise that our expedition were the first people on the planet to see this environment. I definitely shed a tear or two.

 

What advice would you give to someone going on field work for the first time?

Preparation is key - always have a back-up plan!

What do you study at the Museum?

My main interest is deep-sea biology and in particular the diversity, evolution and ecology of the marine annelid worms - the polychaetes. These are incredibly diverse in the deep-sea, the least explored and largest ecosystem on the planet.

 

What are you most excited about seeing/finding on the trip?

Although our main science goal is the retrieval of a set of important colonisation experiments, I am secretly most excited about taking our little underwater robot 'REX' to its deepest depth rating - 200m. I would like to take it below the warm surface waters into the cooler, darker deep waters - the twilight zone - to observe the marine life using this new low-cost deep-sea approach that we are pioneering on this trip.

 

Where have you been previously been on field work?

I have been fortunate enough to be involved in field work all over the world. Mostly it has been in rather cold places (the Southern Ocean, the Antarctic and the North Sea). I am looking forward to a tropical trip for a change!

 

What is your best experience whilst on field work?

The best experience has been our first discovery of the enigmatic Osedax worms whilst on a sampling trip in Sweden. It was incredible to find these bizarre animals living so close to a marine lab, in shallow water. It reinforced to me how little we know even the accessible parts of our oceans.

Now that Tom has returned safely from his botanical trip to Costa Rica, I'll be heading off to the Bahamas with scientists from the Museum and the University of Southampton. Our destination is the remote island of Eleuthera in the Bahamas and most of our time will be spent on a boat.

 

google-earth-bahamas.jpg

(Click images to see them full size)

 

We’ll be using a Remotely-Operated Vehicle (ROV), called REX, to survey the fauna that live in this little explored part of the Caribbean. The really exciting bit is that in some cases this will be the first time that scientists have dropped a camera into these waters.

 

Aside from the observatory work, the team are also looking for a particular worm that likes to live on whale bones. Osedax worms have been found in every ocean in which scientists have looked for them, including the Antarctic, but will they also be found in the tropical waters of the Caribbean?

 

As part of the Museum’s Nature Live programme, I’m lucky enough be joining the trip and I’ll be sending back daily reports in the form of blog posts, pictures and videos. Get in touch with the field trip by using the comments section at the end of each blog.

 

For a chance to experience the trip come to the Museum's Attenborough Studio at 14:30 on 8, 9 and 10 March to see us in a live-video-link to the Bahamas.
